yesterday, it took me all work-day to read this thread from front to back 
and now i want to find the source for the rotary switch but cant find it. help! thanks! 
EDIT: no sooner posted than i found a couple candidates:
- mouser 633-MRX108A-RO
- mouser 633-MRK112A

OK I have a question about the step leds,
I have an idea for a rotary design that will have 4 or 5 leds wired in parallel to be triggered per step, arranged in a star pattern kind of like a clock.
Can the klee drive say 5 3mm leds from each step? |

Nope, not in its native form. But that's not say it can't be done. I had a discussion with someone by PM about driving LEDs (sorry, I've had so many PMs lately, my head can't hold it all), but it would be a relatively easy thing to build a small driver board that could handle the current required to drive how ever many LEDs you wanted.
The LED connections come from two 8 pin sip connectors. If you're using the connectors and plus, you could build a couple of eight wire cables (like the two board interconnect cables) and jump over to this extra board. If you're not using the connectors and plugs, then it could still be hard wired. The board would also be fed with power and ground from the power supply. You may want to not install the 6K8 LED resistors and instead just jumper them, depends on how your transistor buffers are built.
The driver board itself wouldn't be too complicated - just a transistor and a few resistors for each LED. Then you could connect from this board to the LEDs. You could drive a Christmas tree from that.
Cheerios,
Scott

Eh?? Who said anything about a front panel looking like a washing machine? 
The washing machine is purely there as a reference, as I pointed out that most people haven't had the chance to look inside an aircraft cockpit, or a nuclear power station etc etc.
Randal, why don't you post an example of a front panel in say a fpd format or a a Solidworks sldprt format (e-drawings is a free download). You seem to be pretty clued up on what a front panel would ultimately look like (I remember you said in a PM to me that you were an experienced Solidworks user?). Go on mate, impress us! 
FWIW, after all these years as a product designer, I bet half the forum here would like to see how the expert would do it

I'm adding a few customisations:
* Internal clock
* External control of the start/stop and step functions for control of multiple units by the same button
* Output of the random state just because I had the panel space to do so.
I will be implementing the manual (variable) range option however I would like to be able to select the maximum voltage as 1, 2, 4 or 8V. This can be done really easily with a dual gang rotary switch but am having difficulty finding ones that won't cost cost me a kidney (anybody know a good reasonably priced source for such items - rotary switches that is, not kidneys)

Alright - having just started my read on the Build manual for the Klee, now that I have the boards - is there any message through anywhere on e-m, that has suggestions as WHERE to get whichever brands of toggle switches, for the unit?
I've still got 'off-shore' ones from Mode Electronics. But - they're UP to 10 years old, AND no-name. 
I've been keeping my eye out for deals, but now reading the manual - I would PREFER to take Scott's recommendations of NOT going with 'El-CHEAPO' components. 
My ULTIMATE goal - would 100 pcs. of a decent brand name at $1.00 a piece. In a quick search from work tonight, I couldn't find anything close to that.
Not too BAD pricing at Small Bear Electronics, but - the way their On-Off functionality is listed - they ALL look like Momentaries. (On-Off) or (ON-ON).
I'm open to suggestions from anyone for brands that others know as good. (I'm minorly familiar with C&K and NKK, but that's it - quality wise)
Thanks for any help! I see that I'll need 40 toggles for it. I'd prefer to jump up to 100 pcs., if I can find cheaply enough, as I'd like to get a 2nd Klee some day and I do use toggles regularly in projects anyways.
(Side note. I'm VERY happy with my ALPS pots and their pricing, from Small Bear. Purchasing from him regularly now. ) |

Hey Ryk,
On page 11 of this thread I posted about the switches I used. I used subminiature - a bit small perhaps, but I think the Mouser catalog page they're on shows the larger ones as well. Very nice switches, not too terribly expensive.
The most critical switches are the two momentary switches - those are the last one's I'd scrimp on. I got larger ones for mine, and I'm glad I did - it makes punching the step and load a lot easier.
Cheerio,
Scott

Well, the miniature one's are a buck fifty or so in quantities of 100, but they're worth it, if that's any consolation.
Here's the catalog page:

Cheer,

Hi V,
I May as well take the bait, eh?
I already posted at least two very different Klee panel designs in THIS thread. How ever did you miss posting some of your witty repartee' WRT those before this! In fact, you may recall your PM reply to me when I originally asked if you minded that I would post a Klee layout since you were the "official" Klee panel creator. Never did see one from you??? And I've posted panels for other designs around the forums here.
FWIW, closer to NAMM I probably will post some solidworks pics. But not now. (Tho' some here have have seen a few of them off forum for comments and feedback and said nice things.)
As for impressing anyone, I'm not really here for that; only to share and learn. You seem somewhat fixated on repeatedly mentioning my being involved in product design. FWIW, It's a job, like any other. I'm just here to share and learn.
I'm quite sure that more than "half the forum here" could care less about how I might do it! But for some, my thoughts and ideas WRT panels might be seen as helpful. If that doesn't include you, just ignore my posts. Please.
Kind regards, Randal |

Many thanks Scott! Their switch pricings are much better than what we have HERE in the city! I'll be moving to Mountain Switches now.
DL'd the entire catalog. (Wish everyone else's catalogue was as detailed! ) |

AP - Beautiful work!!! I can't believe how fast you're getting that thing together! I wanna see the LEDs in action when you're done.
Ryk - You can sign up for a paper catalog from Mouser (though I'm not sure they will or will not send it to Canada - bet they do). The thing is the size of a telephone book that would challenge even Arnold Schwarzenegger. If anything, you'd save money on the necessary wood pulp based items required in the Room of Thought.
Cheers,
Scott

I'm building the analog board right now, and im wondering what you guys are using for R33? Can I just put a 100k in there? I don't quite understand how the values affect the variable option, which is what im implementing.
thanks,
pete

oops I just noticed that there is a 1k thats goes there. Is that the default value?
thanks

1K is the default value for R33 only if you want 8V fixed range there.
Otherwise, you select the value of R33 depending on how much maximum voltage you want to be able to dial up on your variable range. A larger value of voltage will allow you to swing the variable range around more, but a lower voltage will make it easier to set smaller increments.
On mine, I went for 4V range or so - that allows me to do crazy squiggle things with the voltage, but yet I can set small increments quite easily, also. YMMV.
R33 forms a voltage divider with the variable range pot, which is 100K, so it sets how much voltage will actually be available at the wiper pot. The applied voltage at the top of the divider is 10V. So, if R33 is set for 100K, that should give you around 5V available as the maximum variable voltage:
10V/200K = 50 uA.
50 uA X 100K = 5V.
What voltage would you like to have as your maximum variable range voltage?
Cheerio,
Scott

Ok I put a 150k in there. Is that the value you used Scott? Honestly, I dont really understand how the Klee works. Though after using it for a while, im sure that I will figure it out. Its a challenge for me to wrap my head around the Logic stuff, though im learning fast!
Thanks,
pete
